<DT><B>Description</B><DD>
restorecrtmode restores the original video mode detected by initgraph.
<P>
This function can be used in conjunction with setgraphmode to switch back and forth between text and graphics modes. textmode should not be used for this purpose; use it only when the screen is in text mode, to change to a different text mode.


<P><DT><B>Return Value</B><DD>
None.

<P><DT><B>Windows Notes <IMG SRC="win.gif" ALT="[WIN]"></B><DD>
restorecrtmode is implemented in <A
HREF="../../bgi/README.html">winbgim</A>,
but it does not do any work. This is because both the graphics window
and the text window are always open during any Windows program, so
there is no need to switch back and forth between the two modes.
